High-resolution optical spectroscopy of the hot R CrB star V348 Sagittarii

LEUENHAGEN U., HEBER U. and JEFFERY C.S.

Abstract (from CDS):

High resolution optical spectra of the unique hot R CrB star V348 Sgr are presented and more than 500 spectral lines of 14 elements are identified. The spectrum is very complex and four types of line profiles can be distinguished: a) pure absorption lines, b) P-Cygni lines, c) pure emission lines and d) P-Cygni (HeI) or emission (CII) profiles with central absorption reversal. The spectrum is interpreted as that of an expanding atmosphere of small optical thickness with wind velocities between 150 and 200 km/s. Hydrogen is definitely present in the expanding atmosphere. The absorption line spectrum is very similar to that of the extreme helium stars DY Cen and LSE 78.
